A telescopic device for GQF-Z expansion joint highway bridge is composed of a group of steel side beams and anchors, plus a whole length of rubber sealing strip. The anchor on the outer side of the steel edge beam of the expansion device is welded with the embedded steel bar at the end of the beam, and then the high strength concrete transition section is poured and connected with the beam body. The GQF-D type expansion joint has the characteristics of reliable connection, smooth connection with the bridge deck, sealing and sealing, flexible expansion, stable running and long service life. Bridge suitable for 40mm, 60mm and 80mm expansion.

GQF-Z type expansion joint main material: steel side beam: rolled by 16Mn steel, the section is C shape. Sealing strip: made of neoprene or three yuan ethylene propylene rubber, has good aging resistance, bending resistance performance. Anchor: there are three kinds of anchor, anchor ring, anchor plate structure, highway bridge engineer can choose according to the thickness of bridge deck design. We can refer to: C bridge expansion joint classification and product range of application in detail

GQF-Z type expansion joint is applicable to the design of steam load for the super 20 super 120 hang straight bridge, the curved bridge, skew bridge and ramp bridge, highway and city bridge. Because it is made of steel side beam, bird shaped rubber sealing strip and anchor component. In the bridge body due to the temperature difference caused by mechanical displacement, fixed to the side beam groove in rubber seal can free telescopic folding. Play the role of waterproof and dustproof. The impact force of the moving vehicle is transferred to the bridge structure through the side beam and the welded anchorage member. This type of expansion joint is suitable for bridges with 0 ~ 80mm expansion capacity.
